Lite on features, but neat
It doesn’t have a lot of features (e.g. unlike chess.com which gives comprehensive solution and video) but is exactly a simple problems training app for chess. Very convenient, stable and (I bought all the problems) have a lot of variety. I love the daily problems set which I do everyday now. My only gripe is that the problems are divided a bit too simple as “easy”, “medium” and “hard” but I sometimes encounter easy problems that are very hard and hard that I would suggest medium - suggest problems are not graded by difficulty but number of moves in the solution …
